Specification of Letters lee tent.

Application filed April. 1, 1912. Serial No. 687.6742.

To all wrtom it may concern:

Be it known that I, JACOB T. Cnoonnn, a citizen of the United States, residing at Mulberry, 1n the county of Crawford and State of Arkansas, have invented certain new and useful Improvements in Spring ottoms for Chairs; and I do declare the following-to be a full, clear, and exact descrlption of the invention, such as will enable others skilled in the art to which it apper tains to make and use the same.

This invention relates to improvements in spring bottoms for chairs.

One object of the invention is to provide a chair bottom having an improved means for yieldingly attaching the same to the seat frame of a chair. 7 Another object is to provide a spring bottom for chairs which will be simple, strong and durable in construction and which may be readily applied to new chairs or to old chairs to take the place of the bottoms which may have been broken out of the chairs.

With these and other objects in view the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings; Figure l is a vertical sectional view of a, chair showing my improved chair bottom applied thereto; Fig. 2 is a horizontal sectional view of the same on the line 2---2 of Fig. 1; Fig. 3 is a plan view of the seat frame of the bottom.

Referring more particularly to the drawings, 1 denotes the chair to which the ini proved bottom is applied, said chair com-- prising the usual seat frame 2, to which is secured the upper ends of supporting legs 3. In the opening of the seat frame arranged the bottom frame 4 which corresponds in shape to the shape of the opening in the seat frame of the chair which may be filled in with any suitable material for forming the seat or bottom 5, said seat or bottom being preferably formed of woven .upper side of said frame by strips of cane, ratan, inetah fabric or other suitable material having suffi strength to form said bottom or seat. t

The bottom frame l and the seat or bottom are yieldingly supported position in the opening of the seat frar e the v lower supporting frame (3 to which said bottom frame "it 4. is secured by a series of upwardly and outwardly projecting connecting bars or links any number of which th ir employed said bars or linlzs being p erably loosely connected to the bottom frame 4: and s1 porting frame 6 by eyes 8 formed in he ends of the bars or links as shown.

The supporting frame 6 secured to the chair and held in position to support the bottom by series of short coiled sprin 7 t5 the inner ends of which are secured to a e sides of the supporting while their outer ends are secured to supporting rods 10 arranged between and a their secure ends in the legs of the ch a short d. below the seat frame 2 a shown. arranging the supportii "ran springs 9 it will be sari.w to. frame 4- and the seat frame 5 will ingly supported in. position in the of the chair seat frame.

A chair seat or frame constr cordance with my invention may be e "plli i1 1 to new chairs or to old chairs from the bottoms have been broken a and will form a strong, durable and ate tive s ring seat for the chair.

From the foregoing desrription r connection with the accoinpanfvin dra M ii the construction and 01 ation of the ii tion will be readily unfrlstood Without quiring a more extended ifipliil n.

Having thus described. my uveut nio, what I claim is;
